OBJECTIVE: Cervical cancer metastatic to the para-aortic lymph nodes (PALNs) carries a poor prognosis. Despite extended-field radiation therapy (EFRT), only 30% to 50% of patients will survive 3 years. We sought to examine the treatment regimens used, associated toxicities, and treatment outcomes in patients with cervical cancer metastatic to PALN. METHODS: A retrospective review was performed of all patients with cervical cancer treated at a single institution between January 1, 2007 and November 1, 2014...

Elective neck dissection of the N0-neck is routinely performed during salvage laryngectomy (SLE) for recurrent cancer of the larynx or hypopharynx. The therapeutic benefit of additional neck dissection must be weighed against the risk of increased morbidity. In this retrospective analysis, we assessed oncologic parameters of patients who underwent SLE with concurrent bilateral neck dissection for recurrent laryngeal or hypopharyngeal cancer. We compared these data with patients who underwent primary laryngectomy (LE) with bilateral neck dissection for laryngeal and hypopharyngeal cancer...

Brachytherapy (BT), the use of a locally placed or implanted radioactive source for treatment of an adjacent tumor, is an important component in the treatment of patients with both early- and advanced-stage cervical cancer and is increasingly part of the standard treatment protocol. When it is feasible, many radiation oncologists choose to include a magnetic resonance (MR) imaging examination for planning BT treatment (ie, an MR imaging examination after placement of the applicator but before radiation dosing)...

PURPOSE: Thermoradiotherapy is an effective treatment for locally advanced cervical cancer. However, the optimal time interval between radiotherapy and hyperthermia, resulting in the highest therapeutic gain, remains unclear. This study aims to evaluate the effect of time interval on the therapeutic gain using biological treatment planning. METHODS: Radiotherapy and hyperthermia treatment plans were created for 15 cervical cancer patients. Biological modeling was used to calculate the equivalent radiation dose, that is, the radiation dose that results in the same biological effect as the thermoradiotherapy treatment, for different time intervals ranging from 0-4 h...

Radioresistance remains a major clinical challenge in cervical cancer therapy. However, the mechanism for the development of radioresistance in cervical cancer is unclear. Herein, we determined that growth arrest and DNA-damage-inducible protein 45α (GADD45α) is decreased in radioresistant cervical cancer compared to radiosensitive cancer both in vitro and in vivo. In addition, silencing GADD45α prevents cervical cancer cells from undergoing radiation-induced DNA damage, cell cycle arrest, and apoptosis...

Brachytherapy is a standard treatment modality for locally advanced cervical cancer. In patients with uterine anomalies, the radiation dose to the target volume and the organs at risk can vary depending on the positioning of the brachytherapy tandem implant. However, there have been few reports concerning the use of brachytherapy in patients with uterine anomalies. The present study reports the case of a 55-year-old woman with locally advanced squamous cell carcinoma of the cervix and complete septate uterus...

We report the case of a 50-year-old female survivor of Hodgkin lymphoma (HL), who developed dropped head syndrome (DHS). The patient was diagnosed with HL at 20 years of age, and underwent chemo-radiotherapy, which led to complete remission. Undergoing supplemental therapy for post-radiation hypothyroidism, she had twin babies. She noticed white stains on her neck at the age of 30, and the decolored area gradually expanded. Sixteen years after the radiotherapy (RT), her posterior neck muscle strength began to decline...

Although mitochondria are known to play an important role in radiation-induced cellular damage, the mechanisms by which ionizing radiation modulates mitochondrial dynamics are largely unknown. In this study, human cervical carcinoma cell line HeLa was used to demonstrate the different modes of mitochondrial network in response to different quality radiations such as low linear energy transfer (LET) X-rays and high-LET carbon ions. Mitochondria fragmented into punctate and clustered ones upon carbon ion irradiation in a dose- and LET-dependent manner, which was associated with apoptotic cell death...
